Further insights into the assembly of the yeast cytochrome bc1 complex based on analysis of single and double deletion mutants lacking supernumerary subunits and cytochrome b. Eur J Biochem. 2004;271:1209-18 pubmed..Likewise, evidence of interactions between subunit 6, subunit 9 and cytochrome c1 suggests that a subcomplex between these two supernumerary subunits and the cytochrome might exist. ..
- Saracino F, Bassler J, Muzzini D, Hurt E, Agostoni Carbone M. The yeast kinase Swe1 is required for proper entry into cell cycle after arrest due to ribosome biogenesis and protein synthesis defects. Cell Cycle. 2004;3:648-54 pubmed..Therefore we propose that Swe1, which is required for coordination of cell growth and cell division in G2/M, also has a role in the beginning of the cell cycle. ..
